Abstract: Polydimethylsiloxane-b-(ethylene oxide) block copolymer(DMS-b-OE) was used as compatibilizer for polydimethylsiloxane/polyurethane blends (PDMS/PU) and its effects on morphology, mechanical properties were investigated with SEM, DMA, stress-strain behaviour measurement. The results demonstrated that the compatibility between PDMS and PU was promoted and the mechanical properties were improved.
